Description

Technical Field

[0001] The utility model relates to the technical field of PVC production, in particular to a grinding device for PVC production. Background Art

[0002] PVC was once the world's most produced general-purpose plastic and is widely used. PVC comes in two types: rigid (sometimes abbreviated as RPVC) and soft. Rigid polyvinyl chloride is used for building pipes, doors and windows. It is also used to make plastic bottles, packaging, bank cards or membership cards. Adding plasticizers can make PVC softer and more flexible. It can be used for pipes, cable insulation, flooring, signs, phonograph records, inflatable products and rubber substitutes.

[0003] Most of the existing grinding devices for PVC production can only grind PVC into fixed sizes. When finer grinding is required, it is necessary to replace it with a grinding device of other sizes. In addition, during the grinding process, the PVC material will stick to the grinding roller, resulting in reduced grinding efficiency, which in turn affects the working efficiency of the device.
